Hello,

The “set expression pedal (aka HotKnob) max value” is the parameter that you should assign the CC to. If you assign this CC to the parameter and adjust the CC, you should see the parameters that are mapped to the hot knob update on the pedal UI and in H9 Control. Note that in H9 Control the ribbon control will not move, and on the pedal UI you will not see “HOT +” which normally shows up when adjusting the hot knob using the jog wheel. However, the CC will still adjust whatever parameters are mapped to the hot knob, the easiest way to confirm this is viewing the parameters change in H9 Control.

Let me know if you have any questions.
